The Clocks palette doesn't appear at startup despite I've selected the "Always show palette at startup" checkbox. What can I do?

The problem is most probably due to the fact that the World Clock Deluxe application is hidden after it is opened automatically.

On Mac OS X 10.7 or later, open System Preferences and click Users & Groups. Select your account in the list, click the Login Items tab and, make sure World Clock Deluxe's checkbox in the Hide column is deselected.

On Mac OS X 10.4 to 10.6, open System Preferences and click Accounts. Select your account in the list, click the Login Items tab, and make sure World Clock Deluxe's checkbox in the Hide column is deselected.

On Mac OS X 10.3, open System Preferences and click Accounts. Select your account in the list, click the Startup Items tab, and make sure World Clock Deluxe's checkbox in the Hide column is deselected.

On Mac OS X 10.2, open System Preferences, click Login Items and make sure World Clock Deluxe's checkbox in the Hide column is deselected.

World Clock Deluxe displays wrong times. How can I reset them?

Your problem may be due to the fact that your computer's time zone is incorrectly set. Open System Preferences and click Date & Time. Click the Time Zone tab, click your part of the world on the map, and choose your closest city in the drop-down menu. If you don't use a network time server to automatically set the date and time, click the Date & Time tab and adjust your computer's clock.

If your computer's time zone and clock are both correct but some of your clocks display wrong times, you should check each of them and, if it is showing an alternate text, verify that the associated city is correct. Open the Clocks pane and double-click the clock in the list. If the Alternate text field isn't empty, make sure that the city selected in the list is correct.

World Clock Deluxe doesn't use the system time format. What's wrong?

If your clocks don't use the system time format despite you have set them to use the System Setting format, you should make sure you have thoroughly customized times in the Language & Region (or Language & Text) pane of System Preferences.

On OS X 10.9 or later, open System Preferences, and then click Language & Region. Click the Advanced button, and then the Times tab. Edit the Medium time format so that it is consistent with the Short format and click OK.

On OS X 10.8, open System Preferences, and then click Language & Text. Click the Region tab, and then the Customize button in the Times section. Edit the Medium time format so that it is consistent with the Short format and click OK.

On Mac OS X 10.7 and 10.6, open System Preferences, and then click Language & Text. Click the Formats tab, and then the Customize button in the Times section. Edit the Medium time format so that it is consistent with the Short format and click OK.

Why are some clocks marked with an asterisk (*) in menus?

If you show daylight-saving time transitions in the Clocks palette pop-up menu, in the Dock icon menu, or the menu associated with the World Clock Deluxe icon or clock in the menu bar, clocks that are about to switch to daylight-saving or standard time will be marked with an asterisk (*).

Marked clocks will switch to daylight-saving or standard time within a week. To view when the transition will exactly occur, use the DST Transitions submenu.
